A coupling wire guide is structured to be slidably coupled to a previously introduced wire guide, and is also well suited for stand-alone use. The coupling wire guide generally includes a main body having a distal end and a coupling tip connection to the distal end. The coupling tip includes a coupling portion and a tip portion. The coupling portion defines a coupling passageway having a proximal port and distal port for receiving a previously introduced wire guide. The tip portion includes a distal end surface having an atraumatic shape.
